[Elecraft] K4 CW filtering

[Bill Overstreet]

I need some explanation of how filtering is done in the K4 when in the 
CW mode.


As a comparison, when in LSB mode with 2.2 kHz BW, I can copy CW but it 
is obvious that the full 2.2 kHz bandwidth is available.


Then, switching to CW mode (with APF off and filter BW set to 2.2 kHz) 
there is a significantly restricted bandwidth when compared to the LSB 
filtering.


I thought maybe the CW IIR filter was in play, but I turning it off, 
there is no noticeable effect.


There must be some additional filtering in the receiver chain when in 
the CW mode, but I don’t understand what its characteristics are. Or 
whether can it be turned off or not?


Receiver performance in the CW mode is definitely better, but I would 
like to understand the filter arrangement in the K4.


In general, a technical "theory of operation" manual would be helpful.

Thanks, Bill, K4AJ

Re: [Elecraft] K4 and Mercury IIIs

[Dave New, N8SBE]

According to my most recent 80M Elecraft SSB Net report, both K2RIG and 
W4CBS are running Mercury III amps with their K4s.  One or both of those 
may be IIIs.  Also, K8NU used to run a Mercury amp with his K4D, but he 
recently upgraded to a KPA1500.  He was using a Palomar HF-AUTO as an 
ATU, but I think he ultimately preferred the KPA1500 for both its 
tighter integration with the K4/K4D and also the built-in ATU.


Hope that helps.

We had a total of 15 check ins this week (including the NCS). I'd like 
to thank the relay stations for assisting net control. I hope to see all 
of you again. The net concluded at 09:45 PM ET.


We have a really great group of folks checking in, and I encourage 
everyone in the Midwest and adjoining areas to check in next week.


As a reminder, if you go to https://netlogger.org at the net starting 
time and look for the 80M Elecraft SSB Net, you should see the frequency 
we are using that evening, if we must QSY due to busy frequencies.

[Dave (NK7Z)]

Hello,

Just a short note for K4 owners...  I have a free program which will 
will allow you to both create and launch macros for the K4, from your 
windows computer.  See:


https://www.nk7z.net/macromaster/

The program has a built in editor for creating macros.  It allows for 
swapping macros between people via an import/export function.


Many features, be sure to read the help file, all options are covered 
there...

I listen to the AM Broadcast band using the SSB detector. Max RX 
bandwidth is 5 kHz, which just about optimum for speech. I use it to 
evaluate performance of RX antennas, mostly to make sure they're working 
after storms. Stuff tends to fall on them, like branches and even entire 
trees.


I've never cared about AM TX.

The only things that Elecraft should do to prevent lightning damage are 
to properly terminate cable shields to the shielding enclosure at the 
point of entry, properly terminate power system safety ground contacts, 
the the shielding enclosure, and otherwise practice proper bonding 
within their products.


The rest of it is up to us. About a week ago, I posted a link to 
tutorial slides for talks that I've done on the topic. EVERYTHING shown 
is good engineering practice to prevent lightning damage, and much of it 
also minimizes issues with RFI. Anything that we fail to do is an open 
door for lightning damage.

Re: [Elecraft] K4 Remote: My QTH vs. a friend's, many miles to the north

[Dave (NK7Z)]

Hi again,

Your grounding sounds good.  I suspect the USB connection used by 
Elecraft was standard, and not something that was lightening proof, so 
yes, any manufacturer can do more, the question is why increase the cost 
of the amp to everyone, when there is little chance the protection will 
ever be used?


If there were a preponderance of KPA1500 amps loosing USB drivers, then 
I might agree with you, but so far, your amp is the only one I have 
heard about that took a lightening hit, and the only one I have heard 
about that has lost a USB driver...


If all you lost was the USB driver, then you are a lucky man, go buy a 
lotto ticket today!!  I would expect a lot more to be damaged by a 
lightening strike...


In any case, it is too bad the amp failed, but by that same token, it is 
really good that is all that happened!


As you mentioned a bit ago, the more hi-tech an items is the more 
sensitive it becomes...

Jorge,

I can only go by what you said:

"Last week I experienced a lightning strike"

That sounds a lot like a direct discharge into the shack, so I am
responding to your comment, if that is not correct, please help me
understand what actually happened...

Lightening is strange, it can take out one piece of equipment, and not
touch another...  It all depends on how your shack is grounded, and how
it is bonded.  When grounding commercial equipment, even the path the
wire takes is important...  Curves, straight line runs, etc...

What sort of ground system are you using, and what sort of lightening
protection did you have in place at the time of the lightening event?

Take a look at:

https://www.nk7z.net/building-a-coax-entry-panel/


That is my entry panel.  I am slowly building a ground ring around the
house...  Why?  Because only I can build a system to help reduce the
chances of lightening taking out something in my environment.  It is
after all my home, and my environment, so I can not, and do not, hold
Elecraft responsible for things they can not control.  Elecraft, can
not
be responsible for my grounding, and bonding practices.

Respectfully, in your original question you implied that Elecraft
should
have done more to make the KPA1500 withstand an as yet, correctly
defined lightening event.  Again, respectfully, if you believe Elecraft
failed in some way, then you should say what, and how they failed...
Not imply they should have done more...  That is unfair.

With respect to the weekend-- I hope to see you in the 7QP contest!  I
will be on Sunday, but I fear the Sun will not assist much...  Take
care
my friend...

Hi Dave

I have a panel like yours, each antenna to a discharger, on a copper sheet.
Nothing has happened with the coaxial and antenna switch

Re: [Elecraft] K4 Remote: My QTH vs. a friend's, many miles to the north

[Dave (NK7Z)]

Jorge,

I can only go by what you said:

"Last week I experienced a lightning strike"

That sounds a lot like a direct discharge into the shack, so I am 
responding to your comment, if that is not correct, please help me 
understand what actually happened...


Lightening is strange, it can take out one piece of equipment, and not 
touch another...  It all depends on how your shack is grounded, and how 
it is bonded.  When grounding commercial equipment, even the path the 
wire takes is important...  Curves, straight line runs, etc...


What sort of ground system are you using, and what sort of lightening 
protection did you have in place at the time of the lightening event?


Take a look at:

https://www.nk7z.net/building-a-coax-entry-panel/

That is my entry panel.  I am slowly building a ground ring around the 
house...  Why?  Because only I can build a system to help reduce the 
chances of lightening taking out something in my environment.  It is 
after all my home, and my environment, so I can not, and do not, hold 
Elecraft responsible for things they can not control.  Elecraft, can not 
be responsible for my grounding, and bonding practices.


Respectfully, in your original question you implied that Elecraft should 
have done more to make the KPA1500 withstand an as yet, correctly 
defined lightening event.  Again, respectfully, if you believe Elecraft 
failed in some way, then you should say what, and how they failed... 
Not imply they should have done more...  That is unfair.


With respect to the weekend-- I hope to see you in the 7QP contest!  I 
will be on Sunday, but I fear the Sun will not assist much...  Take care 
my friend...

For Elecraft to protect the amp against a lightening strike as you

Re: [Elecraft] K4 Remote: My QTH vs. a friend's, many miles to the north

[Fred Jensen]

Supported myself during college at the local TV station ... very late 
1950's. Station was on a ridge, we got lots of lightning strikes on our 
tower. The grounding ["earthing"] of the entire station was super 
extensive. We still occasionally lost equipment, mostly the smaller 
uwave equipment outside, despite the grounding.  Direct lightning 
strikes are so intense and large.  Lightning is also an RF event.  What 
happens in a near but safe place can create very large currents in 
nearby conductors.

Hi Jorge,

That device would not stand a strike...  As per the US Weather service, 
(https://www.weather.gov/safety/lightning-power), a typical lightening 
bolt runs around 300,000,000 volts, at 30,000 amps.  That device is 
speced for 4000 volts...


For Elecraft to protect the amp against a lightening strike as you 
described you had, they would need to add a LOT more hardware than that 
to the price of an already expensive amp, and most people would never 
see need the protection.  Hence why they don't even try and protect

Re: [Elecraft] K4 Remote: Station design

[Rick NK7I]

 * Elecraft has no control in how one sets up (or uses) a station.
 * A remote station needs all of the same protection enjoyed by any
   other station; they are the same except one is used remotely.

On the last premise; set up the remote station as if it were any other 
station; RFI and noise mitigation, generator back up power, UPS, 
lightning protection*; GROUNDING AND BONDING, heating and (!) cooling 
(!); again just like any station should appear and operate (even if it's 
stuffed into a closet).


The power supply system should provide for continuous power to the 
network too.  It's MORE important if the station is intended for remote 
ops.  The control operator (local or remote) is required to have FULL 
control over the station operations; plan for worst case events that 
would affect that; loss of network is a key consideration for remote use.


[I have a lot of UPS, one per mesh node included, for the approx one 
minute until the generator switches in upon power failure and one  UPS 
per computer power source to keep the services I provide, online.  
Simply because Starlink and the network takes over ten minutes to 
re-establish with a power loss.  That's a long key down time!]


It is up to the USER (remote in particular) to operate the station 
(remote or local) in a way that does not cause harm (on the air or 
through ab/use).  This means small things like making sure the 
transmitter is not locked on (CW key down, FSK transmit) in the event of 
a network fail so it cannot be unkeyed (use of VOX or macros and memory 
use for sending non-phone message strings)


That's nothing new.  A remote station, is just another station with the 
same needs and planning as any other station; except the goal is to use 
it remotely and the ability to control it at all times during use.


73,
Rick nk7i

* Lightning protection how-to or discussion is beyond the scope of this 
group, but EVERY STATION should have a system in place WITH grounding 
and bonding of every item in the shack, includes every wire that enters 
the building (cable TV, phone, power, DSL) or that sticks into the air 
for radio (tower/mast, sat dishes, antennas).


Even if the station location rarely has lightning.  Properly done, the 
protection system would also help static buildup, from rain, wind, snow, 
dust or any other cause.  Static discharge cause is more than lightning 
and can also damage (or destroy) equipment.


Even then, a direct hit may not save the station but it will show what 
was NOT properly taken care of, what was missed in the protection system.


In some cases, it can even lower the noise floor (MAY, not will).

I don’t think you can expect Elecraft to take care of any safety issues,

You could install a remote camera to keep an eye on things, along with smoke 
detectors and some form of extinguisher, such as those now available for 3D 
printers.
To protect from lightning, you’d need to install antenna switches which can be 
controlled either automatically or remotely.
You also need to install lightning arrestors.
Of course all of this won’t prevent damage if you get a direct strike.
To internally protect a K4 or any other Elecraft product is just downright 
impossible.
“Acts of God” are just what they are and mostly out of our control.

What worries me is having a very expensive device like a K4 connected in a

How to avoid damage to the equipment?

Last week I experienced a lightning strike and the I/O module of my KPA1500
was damaged, what has Elecraft thought to ensure that the equipment is not
damaged?

With the remote K3, what was connected to the network was the remoterig,
with the K4 what is connected to the network is a device worth more than
6000 dollars

So, since the I/O module does not have sufficient protections, what is
Elecraft's recommendation to protect them?

designed, in many cases, to be installed remotely, has been, for example on
the USB connector, built with an industrial USB to USB isolator, and not
just a cheap printer´s USB connector

Re: [Elecraft] K4 Remote: My QTH vs. a friend's, many miles to the north

[G4GNX]

I don’t think you can expect Elecraft to take care of any safety issues, 
especially with lightning.

You could install a remote camera to keep an eye on things, along with smoke 
detectors and some form of extinguisher, such as those now available for 3D 
printers.
To protect from lightning, you’d need to install antenna switches which can be 
controlled either automatically or remotely.
You also need to install lightning arrestors.
Of course all of this won’t prevent damage if you get a direct strike.
To internally protect a K4 or any other Elecraft product is just downright 
impossible.
“Acts of God” are just what they are and mostly out of our control.

Re: [Elecraft] K4 Remote: My QTH vs. a friend's, many miles to the north

[Jorge Diez - CX6VM]

Wayne

What worries me is having a very expensive device like a K4 connected in a
remote place, to the antennas, power and internet

How to avoid damage to the equipment?

Last week I experienced a lightning strike and the I/O module of my KPA1500
was damaged, what has Elecraft thought to ensure that the equipment is not
damaged?

With the remote K3, what was connected to the network was the remoterig,
with the K4 what is connected to the network is a device worth more than
6000 dollars

So, since the I/O module does not have sufficient protections, what is
Elecraft's recommendation to protect them?

thanks,
Jorge

[Elecraft] K4 Remote: My QTH vs. a friend's, many miles to the north

[Wayne Burdick]

Now that Remote is available to all K4 owners, we'd love to hear how you're 
using it. 

For me, Remote has added an unexpected new dimension to HF QRP operation.

At my home station in the SF Bay area, I have a mediocre antenna farm (OCF 
dipole and a 16' vertical). Nothing rotates. Nothing changes length at the 
touch of a button. Birds who fly through my near-field live to tell their young.

Worse, I'm at the mercy of my electrically noisy neighbors.

Fortunately, I have a friend who lives 800 miles north of my QTH. He has huge 
directive antennas on a massive tower, not to mention an unbelievably low noise 
floor. I've been envious of his riparian RF ecosystem for years, mine being a 
desert in comparison.

Now, using K4 Remote, I can virtually operate his station whenever he (or 
someone else) isn't using it. And since I'm controlling his K4 with my own, 
there's no difference in the UI or feature set. I've still got three 400-count 
optical encoders for VFO A, B, and RIT/XIT; QSK CW with AFX stereo; all the 
same computer and software interfaces, and his high-res panadapter on my LCD 
and HDMI monitor.

(It's not just the next best thing to being there. It *is* being there.)

Once he installed the new beta release, I kicked off a new effort: 1-watt CW 
DXCC. With his antennas, it shouldn't take long. 

For example, the other day I was tuning around 20 meters locally (i.e., using 
my own antenna) and heard only a few EU stations, peaking around S5. Three 
seconds later I was using my friend's station -- the band was now wall-to-wall 
S9+ DX. I dialed his radio down to 1 Watt and immediately picked up a few new 
ones.

While many K4 owners will be using Remote with KPA1500s, chasing top spots in 
contests and adding to their 300+ country totals, some of us will be nibbling 
at the fringes, like so many cleaner wrasses on a great white. I hope to hear 
these stories, as well.

Wayne

[Elecraft] K4 REMOTE & OTHER FEATURES now available -- Release R36.BETA2

[Wayne Burdick]

[Repeating posting from this morning, since we quickly updated from BETA1 to 
BETA2 to correct a bug -- Wayne, N6KR.]

With the release of beta version R36.BETA2, our long-anticipated K4 Remote 
feature is now available to all K4 owners. A K4 can be either a client radio or 
a server radio, with no additional hardware or software needed beyond an 
Internet router at each end.

K4 field testers, who have helped us refine and test the Remote experience over 
several months, have described K4 Remote as a "game-changer" and "very easy to 
use." Now we're anxious to help everyone else who's interested in Remote get 
started. 

All we ask is that you Read The Manual :) The K4 operating manual has been 
updated with a chapter on Remote setup and operation. You can find it on the 
radio itself by tapping the "?" button, or on our K4 manuals web page. 

An introductory excerpt from the manual appears below. 

Other new features include:

- "RX AUDIO GAIN BOOST" MENU ENTRY:  This menu entry allows users who prefer 
high overall audio output to specify additional gain.

- AGC THRESHOLD can now be set to values 2 and 3. These lower thresholds may be 
useful for those who prefer more aggressive AGC on weaker signals, such as on 
quiet bands or with preamps OFF.

- DIVERSITY-ON BUG FIX: When diversity is turned on, we no longer copy preamp, 
attenuator, or RF gain settings from VFO A to VFO B. This was creating extra 
work for operators, especially on 160 m. (Also applies on band change with 
diversity already ON.)

- FSK TRANSMIT BANDWIDTH NOW MUCH NARROWER: Now using controlled sigmoidal 
tone-shift method to greatly reduce FSK TX bandwidth. 

Full release notes are attached.

Remote Front Panel Emulation -- Overview


Remote front panel emulation is typically used to access a server K4 from 
another location at your home or property, or one at a location with better 
antennas or propagation. This remote server radio may be your own, or one 
anywhere else in the world that another operator has allowed you to use (by 
prearrangement). A client device is used to emulate the front panel of the 
server radio, as if you were at the server location. Instead, you might be at 
your home, in a hotel room, in an RV – or virtually anywhere network 
connectivity is available. 

The K4's implementation of remote makes such operation simple, seamless, and 
immersive. You'll have complete control over the distant station. No special 
interface devices are needed – just a router at each end. There is also no need 
to change your K4's cabling for computer logging, data modes, etc. The client 
seamlessly routes commands, data, and audio from these to the server as 
required. 

Several client devices and applications are supported: (1) another K4, (2) our 
K4/0** compact front-panel unit, or (3) our VK4 Windows application**, or (4) a 
third-party iOS** application. Other apps and platforms may be available in the 
future. (**In development.) 

A K4 used as a client can be disconnected from the server, when desired, to use 
the radio with local antennas. The K4/0 is a control-only device (no RF), with 
the same display, knobs, and switches as the K4 itself, in an enclosure just 4" 
deep.

BUG FIX
---

- NON-FT RADIOS UNABLE TO DO REMOTE CONNECTION: In rev R36.BETA1, one of the 
Remote host commands ("RRT;") was blocked for non-FT radios.


NEW FEATURES


- REMOTE SETTINGS BUTTON ADDED TO LCD: There's a new button ("globe" icon) in 
the lower left-hand corner of the LCD, next to the "?" (INFO) button. Tap this 
to access the client or server settings screens. Refer to the REMOTE feature 
details below, and the REMOTE section of the manual, for details on client and 
server setup.

- REMOTE FRONT PANEL EMULATION (AKA "REMOTE"): The new Remote feature allows 
you to easily control a K4 transceiver anywhere in the world over the Internet. 
The K4 can act as either a client or server, and no additional hardware or 
interface devices are required beyond a router at each end. Additional client 
devices and software are in development, including our K4/0 remote front panel 
unit, VK4 Windows application, and a third-party iOS app. (Additional client 
software applications may be developed in the future, thanks to the K4's large 
host command set and streaming capability.) 

- REMOTE FRONT PANEL EMULATION DOCUMENTATION: The latest K4 operating manual 
includes a comprehensive section on setting up Remote. Please read this section 
carefully if you plan to use your K4 as a Remote server or client. To get to 
the REMOTE section, start at the Table of Contents (under "III. Operation"), 
then click on REMOTE near the bottom of the list.

[Elecraft] [Elecraft-K4] Elecraft 40M SSB Net Report

[Dave New, N8SBE]

[Edited. Reason: Changed K8NU's name from Eric to Carl (sorry about 
that).]


7280 kHz, 1900 UTC Sunday.

Steve, WM6P, the usual NCS, was absent this week, so Dave, N8SBE took 
the net with Brian's, K1NW, assist as a relay station.


Thanks to the following check ins (w) and relays (rel):

   Call   State Radio/Amp Name
1  N8SBE  MIK4D/KPA500Dave (w),(op)
2  K1NW   RIK4D/KPA500Brian (rel),(w)
3  K8NU   OHK4D/KPA1500   Carl (w)
4  W9EJB  INK4D/KPA500Ed (w)
5  NK9A   MIFT710/SB-200  Stan (w)
6  WA8SAJ OHK4D/KPA500Jeff (w)

(Entries with (c/o) indicate a 'one and done' station that checked out 
during the 1st round. (n/h) failed to respond during subsequent rounds.)


We had a total of 6 check ins this week (including the NCS). Thanks to 
the relay stations that helped this afternoon. Very nice hearing from 
everyone today, in spite of the double whammy of C-Class flares in the 
last couple of hours, resulting in an A index of 12. 40M was essentially 
dead. Hopefully we'll have better propagation next week. I hope to see 
all of you again. The net concluded at 19:11 UTC.


We have a really great group of folks checking in, and I encourage 
everyone in the Eastern US and adjoining areas to check in next week.


73,

-- Dave, N8SBE

[Elecraft] K4/0 control unit at Visalia

[Wayne Burdick]

If you’re at Visalia today, please drop by to check out our early prototype of 
the K4/0. This unit has a front panel identical to the K4’s, but it’s only 4” 
deep. It’s ideal for remote control of your K4 (or a friend’s) when space is 
limited.

Full technical details will be provided later.

Re: [Elecraft] K4 Remote Lives and Breathes!

[Gregory Mitchell]

This is why Elecraft needs to get serious about having IPv6 support in the K4. 
Because of stateless auto config, a minimal support would just be to enable 
stateless auto config on the network interface and provide the ipv6 address on 
the menu as readonly.

a real pain to setup and keep connected. Finding a host provider that 
would permit a reverse tunnel is a challenge, few will do this.

This issue is real. A problem is also there is quite many port forward
configurations to setup as one setup a station.

There is methods to punch through NATs, and I hope one have chosen to
use an approach that does this. One is to operate over a VPN that have
these abilities. Another is to use a standard tunnel usinging say TLS
that also include the punch-through capabilities.

Also, IPv6 is starting to replace the IPv4 NAT/CG-NAT hell. It's been a
long coming for sure, but there is plenty of signs it is happening.
While initial release may be IPv4 limited, IPv6 should be high up on the
list of thigns to fix if it is not already handled. This should not be
relevant only for the K4, but any device.

When wearing another set of hats, I work on these issues.

Re: [Elecraft] K4 Remote Lives and Breathes!

[Rick NK7I]

As (other) Rick says, port forwarding varies between routers; but the 
two key points to research for your router are:


1)  Assign (reserve) the K4 MAC(s) to specific IP addresses, so the 
K4(s) is/are ALWAYS at the same LAN IP address (reboot the K4).
2)  Port forward 9204 to the K4 (only one can be shared with the 
outside, if more than one K4 on the LAN) IP address.


You may want to make sure that a password is made within the K4 (instead 
of anyone) so you have some access control.


If you have (like me) Starlink or other CGNAT using ISP, then it gets 
more complicated and probably isn't a topic to be discussed on this list.


Across my Starlink LAN (I have two LAN), it's working beautifully and 
should be available 'real soon now' for public beta... have some 
patience yet while the field test team runs it through it's paces and 
some spit and polish are applied.

I faced such a dilemma some years back when it looked as though we would
need to rely on a cellular router for an ISP.  Fortunately, that didn't
become a permanent solution.

My solution was setting up an AWS instance to which I set up a reverse
SSH tunnel from home and then I could SSH to it from elsewhere and
connect to the reverse tunnel.  Conceptually it's somewhat like a VPN
only it had some manual steps in place.  I now have a similar setup from
a Raspberry Pi running AllStar at a repeater site that connects to a
local system and sets up an SSH reverse tunnel end point.  I did try to
set up a Wire Guard VPN a few years back but had no luck  Perhaps I need
to revisit that idea since things have had a few years to mature,
including me!

Hi, Dave. I don't think it will be much of an issue. With many ISPs,
external IP addresses change rarely. If your ISP is changing addresses
frequently, consider using a DDNS server like no-ip.com. I have tested K4
Remote using a DDNS string in lieu of a hard-coded WAN address and it works

While initial release may be IPv4 limited, IPv6 should be high up on the

A way around this is with the use of a central server, which isn't usually
free. Remote TX works in this way but uses a Raspberry Pi. I note they
support the K3. https://www.remotetx.net/

 - Cabling changes required: *ZERO* - leave both stations in their local
 configuration. You do need a way to turn on a remote K4. I'm using N6TV
 "K-ON" dongles and remote power switches. I think you can also do it from a
 connected KPA1500 and KPA1500 Remote. No need to leave anything powered on
 when not in use.
 - It's *dead simple* to connect - just specify an IP address on the
 client (control) K4 and set up one port forward on the LAN router at the
 server (remote radio) site. Passwords will prevent unwanted intrusion.
 (Compare to over 100 parameters that have to be set up between pairs of
 RRCs - and they only work one-way!)
 - Connection takes about a second.
 - It's bi-directional - any K4 anywhere can control any other K4
 anywhere. No hardware asymmetry.
 - CW sidetone and Voice monitor are local, so unaffected by latency.
 - Use the keyer inside the client K4 or an external keyer.
 - Plays nicely with loggers like N1MM. They see the local K4 and don't
 realize it's controlling a remote radio.
 - You can update the firmware in both radios from the K4 at either site.

I've been an avid remote op for a decade now and this is better than I
expected, like K4 itself well worth the wait. Hang in there, folks,
it's really coming. Really.

Re: [Elecraft] K4 missing features

[G4GNX]

Maybe it depends on the individual setup.

Despite using a steerable double mag-loop for RX, the urban noise is 
horrendous. I don’t find the K3S NR to be particularly good and I’ve placed a 
BHI Parametric Equaliser NR box in line. For me, it doesn’t do a great deal - 
except for one day last week, where the signal I wanted was strong (S9) and 
about equal to the ambient noise. I then found that I could null out the noise 
entirely with the BHI unit, giving me near armchair copy. When the wanted 
signal is below S9, noise reduction results in degradation of the wanted audio 
to a point where the NR is non-effective.

Currently, I find the K4D noise reduction works quite well, albeit using a 
different RX antenna.

As Wayne has already stated Q1 2024 and we’re not there yet, why would you 
expect a different answer at this point?

In no particular order:
1. General coverage, the button still does nothing.

3. Remote operation via Ethernet

In addition, with the K3 there was an update to the firmware which

allowed

VOX to be turned off when the radio was turned off/on. I keep forgetting
and accidentally catching my paddles on my K4...

Now that higher data rates have been approved for the USA, any chance of
fixing the issue where the K4 struggles with Pactor (dropping PTT results
in truncated data transmissions due to TX to RX timing issue), The fix is
to add a 20 mS PTT hold on delay and consider speeding up the throughput

reduce latency too. The same issue with the K3 was fixed in a week of

Now that we have moved into Standard time and have shorter daylight

Re: [Elecraft] K4 missing features, was OT: The 4-track mind

[Tim Tucker]

I got tired of waiting for special subtraction NR and decided to do
something about the lousy K4 NR on SSB. I bought the BHI Dual Inline NR
module and the results are impressive. I will publish a video soon. Anyone
who says that better NR won't help you make more weak signal contacts,
especially if you're in the big city, doesn't know what they are talking
about on this subject. That plus the decreased fatigue factor...

The last thing we heard from Wayne about missing features was that the
Remote Software would be released as Beta in Q1 2024. Every other ask about
other features has been met with radio silence for months. Expect more of
the same at this point.

[Elecraft] K4 missing features, was OT: The 4-track mind

[Dave]

Wayne, if you can return to a single track mind for a moment, any update on
when the K4 missing features will be finished?

In no particular order:
1. General coverage, the button still does nothing.
2. Pre-distortion
3. Remote operation via Ethernet

In addition, with the K3 there was an update to the firmware which allowed
VOX to be turned off when the radio was turned off/on. I keep forgetting
and accidentally catching my paddles on my K4...

Now that higher data rates have been approved for the USA, any chance of
fixing the issue where the K4 struggles with Pactor (dropping PTT results
in truncated data transmissions due to TX to RX timing issue), The fix is
to add a 20 mS PTT hold on delay and consider speeding up the throughput to
reduce latency too. The same issue with the K3 was fixed in a week of being
reported.

Re: [Elecraft] K4 discussion on groups.io

[Mark Musick]

Hi Dave,
I can think of three reasons why in-depth discussion of the K4 is not taking 
place here on this reflector.
The biggest reason is this reflector does not support HTML or attachments. With 
the K4 being able to attach screenshots of the K4 display is very important in 
trouble shooting and answering questions about settings.
The second reason is the file support on the K4 reflector. Where files can be 
deposited for subscribers to access at will. This reflector does not support 
that kind of depository. This reflector does have an archive like the K4 
reflector, but in my opinion the search capability on the K4 reflector is 
superior.
The third reason is , while this reflector has served us well when Elecraft had 
only a few products, now it has become a real navigation issue with so many 
products. Yes, you can set rules to get only those K4, K3, etc. to go to a 
certain folder, but that requires the sender to put the appropriate subject 
line in. This doesn't always happen. The K4 reflector example is people will 
change the discussion of a thread and not update the subject line. On the K4 
reflector or the KX reflector you know the discussion is only about the K4 or 
KX radios.
Fourth on the group.io reflectors there is a dedicated administrator. Back in 
the day it was easy for Wayne and Eric to administer this reflector now with so 
much activity it is hard for them to do that. They have now passed that on to 
Keith. Keith's job is to fix K3s and K4s. I would prefer as a customer that he 
continue doing that and not worry about administering this reflector.
As to being a nonmember of groups.io, it is a simple task to join groups.io and 
subscribe to any groups/reflectors you wish. I belong to eight groups, all 
related to amateur radio.
Also, I have mentioned before you don't have to own or even aspire to own a K4 
to join the K4 reflector. There are subscribers there that their main interest 
is SDRs in general etc.
And one more reason. There are subscribers on the K4 reflector that only own a 
K4 and no other Elecraft equipment and they don't want to filter through all 
the other discussions about Elecraft equipment they don't own or care about. 
They are not going to subscribe to this reflector.
I hope that explains things for you Dave. Sign up on the K4 reflector and learn 
more about it. You are more than welcome there.

73,
Mark, WB9CIF

why not discuss it on this open group that is run by Elecraft?

I guess this group doesn't allow attachments, so the screen shot didn't

I think your description is great! It covers the information thoroughly 
and provides all the info needed to subscribe to a group.


One thing I would add is, once you're subscribed to one or more groups, 
those appear on the Your Groups list. Next to each group name is a link

Hi Magnus,
I take it you are not familiar with groups.io so first groups.io is a web-based 
collective of lots of different reflectors. Someone else can probably give a 
better description.
Open your browser and type in groups.io and it will take you to their sign in 
page. Once you are a member of groups.io you can subscribe to any of the 
reflectors using groups.io.
I'm currently subscribed to eight different reflectors that use groups.io.
One of those eight is the Elecraft-K4 reflector.
Once you're on groups.io you can browse the list of reflectors. Type in 
Elecraft-K4 and it will ask for information for you to subscribe. Then Alan, 
G4GNX. the reflector administrator will review your information and then you're 
in.
Then you will receive any emails that are posted to the reflector. You will 
also have access to the files section where you can download files that have 
been deposited there containing information on macros, answers to many 
questions about the K4 etc.
If you are interested in the Elecraft KX line, there is a groups.io reflector 
for the KX line. The KX3, KX2 and now it also includes the KH1.
If you have more questions, fire away. You can email Alan, G4GNX with any 
specific questions about the K4 Reflector.

[Elecraft] K4 AT tune problems with KAT500 firmware 213

[Andy Durbin]

"Yeah, I flashed to 2.13 from 1.75 this weekend, and at first things seemed to 
be OK, but last night when running the 80M SSB net, I kept having the tuning 
change unexpectedly and my KPA500 kept faulting out. "

Hard to make any useful comment without knowing a lot more about your 
configuration.   However, this is the first report I have seen of any 
regression with beta 2.13.  I'd suggest you email support and include your 
KAT500 config file.

I'd be happy to try to reproduce your problem but I don't use an Elecraft 
transceiver and can't test the AUXBus interface.  If you are not using AUXBus 
please say how your KAT500 is controlled and what KAT500 mode you use when 
operating.

Re: [Elecraft] [Elecraft-K4] K4 AT tune problems with KAT500 firmware 213

[Dave New, N8SBE]

Bob,

Yeah, I flashed to 2.13 from 1.75 this weekend, and at first things 
seemed to be OK, but last night when running the 80M SSB net, I kept 
having the tuning change unexpectedly and my KPA500 kept faulting out.  
This was the issue I was seeing on 2.05, which caused me to move back to 
1.75 several months ago.  I had not had any recent issues on 80M until 
re-flashing to 2.13.  It got so bad, that at some point, the K4D stopped 
putting out ANY power, and I had to re-boot the K4D to get my power 
back.  I don't use the TUNE LP, but rather hit the TUNE button on the 
KAT500, then tap TUNE on the K4D to start the tuning cycle.  The K4D ATU 
is bypassed.


No, I haven't erased all my KAT5000 tune memories - that would entail a 
lengthy re-learning process that I was not keen to do, yet.


There is definitely a change in tuning behavior going from 1.75 to 2.13, 
and at least for me, it's definitely NOT an improvement.

Are you holding down TUNE LP for the entire tune cycle, waiting for a 
match?  That's not how it works.


Also, did you try clearing tuner memories as I previously suggested?  
Or using a dummy load?  It may help since the tuner may start the 
search at a poor match solution from memory.


Does the same problem happen if you use CW mode or FSK mode to produce 
a carrier (tap XMIT in FSK)?


If so, and if the K4 ATU bypassed, it sounds like you have found a new 
bug in the new KAT500 firmware that cannot be resolved by posting to 
this group.


Anyone else here using KAT500 Beta firmware 2.13?  Do you see the same 
problem?


Please report all the details to Elecraft support.  They may ask for a 
log trace if the KAT500 supports that.


Good luck.

Bob the KAT500 tuner works perfectly with firmware 175.  Firmware 213 
seems to converge to an asymptotic reactance instead of 50 ohm match.  
The bad reactance is what causes the K4 to abort the tune cycle.  The 
KAT500 stays in tune unless I clear it.


I've checked everything else numerous times.  Yes the K4 tuner can 
find a match always with no problem,


Bob, the only thing I am changing is the KAT500 firmware.  No cables 
or settings on the K4 are changed.


Getting the hi swr message for tune mode and aborting the K4 tune 
cycle  is going to make it very hard to use an external tuner 
automatic or otherwise.  What does the K4 need to do about high swr in 
tune mode?


Unless there were some hardware changes to the KAT500 that I am

[Elecraft] K4 Production Software Rev. R34 Now Available

[Wayne Burdick]

Release 34 is being promoted to full-production status. This means it will be 
installed on all new K4s. We also encourage existing K4 owners to perform the 
update. The attached release notes provide a summary of all changes since the 
last production release (R33).

I'd like to thank all of our field testers and beta testers for their diligence 
in identifying issues that required attention. As a result, this is the best K4 
software yet.

73,
Wayne
N6KR



== R34 (PRODUCTION) 


Sept. 15, 2023


NOTE


The release notes below are a merge of all R33 beta 1/2/3/4 release notes, 
showing everything that has changed since the R33 production release.



NEW FEATURES


- SUPPLY OVER-VOLTAGE MEASUREMENT: If the K4's supply voltage is found to be 
excessive, an alert will be displayed. If the condition persists, the radio 
will be powered off for safety purposes. Note: Max supply voltage is specified 
as 15 V.

- ADDED "TX MONITOR METHOD, VOICE" menu entry: When this menu entry is set to 
"Fast", all speech processing effects and delays are removed from the voice 
monitor.

- UPDATED BUILT-IN OPERATING MANUAL TO REV C29: This edition includes a number 
of corrections suggested by K4 users.

- AGC SPEED SETTINGS: AGC speed (slow/fast) is now correctly stored per-mode 
rather than per-VFO or per-band. (Also see related bug fix below.)

- NEW APF BANDWIDTH: The CW audio peaking filter now has three settings: 30, 
50, and 150 Hz. The new 150 Hz setting allows APF to be used with faster code 
speeds.

- THREE QSK METHODS: The TX QSK Method menu entry now has three settings. 
Method 1 is unchanged from the last production release; it uses slightly longer 
mute times to create the cleanest possible QSK. Method 2 is the same as the 
original, except that it uses a new DSP algorithm that results in a bit more 
recovered audio. Method 3 is is the same as Method 2, except that some users 
report that it provides reduced artifacts (as compared to Method 2) when using 
the internal keyer at speeds of 47 WPM or higher. NOTE: With all three 
settings, the primary goal is to eliminate "clicks," "thumps," or other 
artifacts that may occur when operating near very strong signals (S9+). Such a 
signal must be present within +/- 2 kHz of the K4's VFO setting in order to 
evaluate the various QSK methods. Otherwise there are no artifacts at all.


-
BUG FIXES
-

- "NO RECORDED MESSAGE" BUG: When doing AF RECord, this message would be 
displayed if the recording filled the 90-second buffer.

- MESSAGE CHAIN/REPEAT FIX: CW/FSK/PSK chained and repeated messages are now 
correctly spaced.

- DETECTION OF ESC ON LOCAL KEYBOARD: With a local keyboard plugged into the K4 
for TX text entry, the ESC key now properly terminates messages.

- DIV LED now turns on if diversity is in effect at power-on.

- SOFTWARE UPDATE FIX: 'Check for Updates' now correctly updates all release 
selections with the latest revision numbers.

- TRANSMIT STATUS INFORMATION FIXED: Previously, in some cases power output 
would be displayed incorrectly, e.g. showing a nonzero value during receive.

- MSG REPEAT TRUNCATION FIXED: Previously, repeating a message with more than 
24 characters would result in truncation of some portion of the message. 
Messages can now be up to 60 characters.

- ELIMINATED "MOTORBOATING" (4 Hz cycling of transmitter when MIC gain = 80).

- ELIMINATED VOICE MODE POWER SPIKES: Previously, asserting PTT could lead to a 
brief spike in output power ahead of normal transmit audio.

- XVTR CONFIGURATION: Transverter configurations are now correctly maintained 
after software updates.

- XVTR QUICK MEMORIES: These now function correctly.

- DVR "NO RECORDED MESSAGE" bug fixed.

- DVR VOICE MESSAGE PLAYBACK CLICKS: The beginning and ending of buffers are 
now truncated by 21 ms to help mask any mic clicks recorded in the message.

- DVR CHAINING: Sometimes when chaining multiple messages, one of them may not 
have played, but the radio would have stay keyed up for the remaining time as 
if it were playing.

- AGC SETTINGS: A/B VFO swaps and copies no longer result in loss of the 
operator's AGC speed setting. Similarly, settings are no longer lost when the 
text decoder is used.

- TX ANTENNA SELECTION: TX ANT settings that are invalid, such as XV OUT on an 
HF band, are no longer allowed. Previously, it was possible to inadvertently 
get into this state with a remote-control command.

- TX GAIN SETTINGS: In rare cases, per-band transmit gain calibration data was 
becoming altered as a side-effect of a band change, swap, etc. This should no 
longer occur.


---
FOR SOFTWARE DEVELOPERS
---

- RU/RD COMMANDS: These encoder up/down simulation commands now work when the 
RIT/XIT offset knob is assigned 

Re: [Elecraft] K4 and Yamaha CM-500 Mic?

[George Danner]

Pete,
I'm using a CM500 that is a year or so old. It replaced one that finally
fell apart and I was tired of gluing it back together.
When I replaced the headset, I did not need to make any adjustments!

I went from a K3 to a K4 with the Yamaha headset plugged into the rear
connectors.
My Mic gain on the K4 is set at 12. TX rear mic configuration is Bias ON
Preamp OFF.

Re: [Elecraft] K4 and Yamaha CM-500 Mic?

[Pete Smith N4ZR]

My CM-500 is about 4 years old, and shedding ear-pads, but it works fine 
with my K3.

I also use the CM-500 on my laptop to record a radio show.  I had to

late-production CM-500s just tend to have low microphone sensitivity.

Question:  Is it reasonable to expect that I’d have to have the mic

Re: [Elecraft] K4 and Yamaha CM-500 Mic?

[Alan Bloom]

I had never used my CM-500 on a K3 so I can't do that comparison. But on 
the K4 I had to turn on the internal mic preamp and set the mic gain all 
the way to maximum.  That seemed to give about the correct level - I 
could talk at normal loudness to get 5 on the ALC.


I also use the CM-500 on my laptop to record a radio show.  I had to 
turn up the gain close to max on the computer as well.  I think

Do the headphones work?  Are you sure that the mic is plugged all the 
way into the jack?

Re: [Elecraft] K4 and Yamaha CM-500 Mic?

[David Herring]

Actually, I had (have) this very same problem and brought it up on here quite 
some time ago.  CM-500, mic and phones plugged into proper jacks on rear, 
preamp on, bias on, mic gain at max, mic right at my lips, and I still have to 
talk very loudly to get any response out of the ALC meter.  I got another 
CM-500 and swapped it in, and it was better…I didn’t have to talk as loud, but 
still way louder than I’d like or should have to. 

I never did puzzle out a solution for this.  So if I need or want to get on SSB 
and can’t talk loud (say like if the XYL is trying to sleep in the next room), 
I put another mic on the front connector and have no problems getting plenty of 
response out of that, even if talking in a hushed voice. 

Oscar, if you find a solution to this, please be sure to post it on here…I’d 
like for this work…failing that I might try someday to find a different 
headset/mic combo...

Dave - N5DCH

Don't know what's different, but those are my settings and result.

Re: [Elecraft] K4 and Yamaha CM-500 Mic?

[G4GNX]

This may sound like a silly question, but are you sure you have the plugs in 
the right way round? i.e. Not swapped over.

AFAIK this problem has not been reported on the K4 reflector and I know other 
folks are using them.

Re: [Elecraft] [Elecraft-K4] Elecraft 80M SSB Net Announcement

[Dave New, N8SBE]

Alan,

Yes, 80M being what it is even at 9PM in the evening here in Michigan.  
I'm afraid so.


If anyone would care to start up a west coast net later in the evening, 
they are perfectly welcome to.


Note that there are 20M and 40M nets earlier in the day.  In particular 
the 20M net gets check ins from both coasts, and sometimes from Great 
Britain and New Zealand, depending on conditions.

Now that we have moved into Daylight time and have longer daylight

Your net control this week will be Dave, N8SBE.

Hope to see you this evening on the net.

Re: [Elecraft] [Elecraft-K4] Elecraft 80M SSB Net Announcement

[Dave New, N8SBE]

Rick,

Understood.  We've almost never gotten any check ins much west of Texas. 
 It would be great to get more folks in the middle of the continent to 
act as relays, to help pull in West Coast folks, etc.


Sorry we couldn't hook up.

Re: [Elecraft] K4 Rx is awesome...

[David Gilbert]

He never said what kind of antenna he was using.   A lossy antenna is 
much worse on transmit than it is on receive.  You can easily tolerate 
20 dB or more loss on receive (for pretty much ANY rig) ... but not on 
transmit, especially in a contest like FD where there is tons of QRM on 
the other end.


The K4 is a very fine rig, but not because of anything he claimed.

I’ve been using my K4 at 100W (per the FD rules) this afternoon on several 
bands.
I am 1D OR.
I can hear many many stations but hardly any of them can hear me.
To me, this means that the K4 Rx is bomb-proof, sensitive, selective, and just, 
well, awesome.
If the other stations had better receivers, they might be able to hear me 
calling them.
They are obviously bogged down with on-site overload/spurii/phase noise etc.
What a pity.
I gave up replying hopelessly to CQFD’s from other 100W stations and went and 
did some woodworking instead.
Much more satisfying. Oh well….

Re: [Elecraft] K4 Rx is awesome...

[Walter Underwood]

Some practices vary with the type of contact—casual, contest, organized program 
(SOTA/POTA), event (JOTA, Field Day), DXpedition—and some are just good 
practices. This document is a good consensus description, with a lean towards 
contesting and DXpedition practices. It is called “Ethics and Operating 
Procedures for the Radio Amateur” and was developed by experience European hams.


https://www.iaru-r1.org/wp-content/uploads/2021/01/Eth-operating-IARU-ENGLISH-version3-2010-amended-2021.pdf

I also recommend the ARRL Operating Manual, though I haven’t read a recent 
edition. I actually have it ready to pick up at my library right now.

https://home.arrl.org/action/Store/Product-Details/productId/114292

The numbers are usually “serial numbers”. They start with 1 for your first 
contact and increase with each contact.

Re: [Elecraft] K4 Rx is awesome...

[Karl W Hubbard via Elecraft]

I tried driving out to my local ham fest location as indicated on the ARRL 
website, but no one was there, and then went to the past site at the high 
school football  stadium. No one was there either. 
I consider my self a newby, don’t even know the etiquette for contests or 
“interrupting” some SSB rag chews I hear on my KX3. People might assume on a 
look up on QRZ that I am an “experienced” ham and conclude that I’m one of 
those A h0l*s. I am  still having to hold a copy of the ARRL band plan in my 
left hand as I dial in frequencies and bands with my right! Reading the 
instructions as I go. No Elmer’s here. 
 Questions like: Do you or if so why do some repeat both call signs of 
participants of a QSO vs just your own? Are the numbers at the conclusion of a 
QSO “ you’re number 28” assigned by the contestant just a way of confirming or 
tabulating a QSO?
I guess it’s similar to talking to air traffic control with flying. Most of ATC 
conversation with rapid fire instructions is anticipation, but even then I had 
trouble reading back directions and squawk numbers etc. I think I must have 
some auditory dyslexia, even though my age adjusted frequencies of hearing are 
very good. 
I am limited by my antenna arrangement, and thus ability to transmit 
effectively with 100W running through my KPA100. I would think it becomes a 
sort of chicken or the egg issue when it comes to QSOs if you have availed 
yourself of all reasonable antenna options (but  I am not erecting a 60 foot 
tower in the back of my building  or mounting my 30 ft MFJ mast with 24 ground 
radials spread over the parking lot) and the only weapon left is transmission 
power. But the easier it is for people to hear you, the more enjoyable the 
radio can be and your communication skills snowball. I’m 68, and in excellent 
health, so hopefully I might have a few years at it. I am looking at taking the 
plunge next year and getting the K4D and the KPA1500 but want to increase my 
knowledge base and will need to upgrade my Buckmaster 300W 7 band OCFD 
currently in use to the 3000 W version. I cheat on CW with keyboard encoding 
and decoding on the KPX3 set at 15 WPM  although all I seem to get on the KX3 
is decoded gibberish**E*EE ** etc.
Finally, how much more sensitive is the K4 for signal reception compared to the 
fully filtered  KX3?

At W6BX, W6JTI and I, also octogenarians, worked you on at least one 
band. We were QRP with a K3/P3/SVGA, with the entire station on battery 
power.

The K4/at is a delight to operate anytime; this last weekend it was used 
in the /Field Day Event/


I ran mine @ 20watts on 40 & 80 meters CW via a wire dipole on a city lot///

Interesting conclusion.

What a pity.

I gave up on SSB on FD more than ten years ago. Instead, have been doing 
FD QRP with W6GJB and W6JTI. There are still guys who haven't been on 
the air in the year between, and some long pauses after a QSO, but 
that's the exception.

Re: [Elecraft] K4 Rx is awesome...

[Al Lorona]

> I can hear many many stations but hardly any of them can hear me.
The most likely reason for this is operator inexperience, which is a perennial 
problem on Field Day. It's great that lots of people who don't usually get on 
the air, get on the air... but the side effect of this is a lot of really poor 
operating habits.

The biggest problem this year, in my opinion, was not identifying at the end of 
each contact. Many ops who were running on a frequency simply would acknowledge 
receipt of the exchange, then just stop transmitting and listen for the next 
caller. Here's an example:

W4---: CQ Field Day, this is W4---.
W3--: This is W3--.
W4---: W3--, I'm 2A Georgia.
W3--:  Thanks, I'm 4A Western Pennsylvania.
W4---: Got your 4A Western Pennsylvania. Good luck in Field Day!


See the problem? This would sometimes continue for 5, 6, or 7 contacts, with 
the W4 never sending his own call. So, be me for a minute: there I am, waiting 
to call the W4, except I don't know he's a W4 because he hasn't said so, and 
neither has anybody else. After the first 20 or 30 times this happened, I 
stopped waiting around for these stations to finally identify themselves.

Once, when this happened for about 6 contacts while I waited around to work a 
strong station in Georgia who refused to identify, I became frustrated and 
transmitted, "Hey, Old Man, you need to ID after each contact!"  The guy 
immediately came back, "Let me tell you, young man, that we're all Extra class 
operators here who finish in the Top 10 every year, so you're not going to 
lecture me on how I should operate!"

I went to CW after this and found the operating to be a lot better. I still 
heard the problem I just described, but not as frequently as on phone.
Another common malpractice was people who were calling CQ, and who would 
receive a response to their CQ, but then would tell the caller to send his 
exchange first. This isn't the way you do it. The CQing station always sends 
its exchange first, then turns it over to the calling station, so that the 
CQing station can acknowledge receipt, identify, and stand by for another 
caller.

I feel like we go over this after every Field Day, and nothing has ever 
changed. I feel like Get Off My Lawn Guy right now.

If you're in a club that's planning a Field Day operation, you need to take the 
April or May club meeting and help people practice the Field Day exchange 
protocol with mock QSOs. It's getting really bad on the phone bands during 
Field Day.
(I didn't mean to subtract from your enjoyment of your new K4. I hope it turns 
out to be a great rig for you for many years.)

Regards,

Al  W6LX

Re: [Elecraft] K4 Rx is awesome...

[David Gilbert]

That falls more under the category of lore than science.  By all 
accounts the K4 has a terrific receiver, but of the several possible 
reasons for what you experienced your receiver is at least a couple 
notches down the list.

Two likely reasons. 1) their receive noise; 2) your antennas.

Re: [Elecraft] [Elecraft-K4] K4D with KAT4 Tuner

[James Bennett via Elecraft]

OK - surprised, I am - not one single offer for my K4D that I posted on 
Tuesday. So, I suppose I need to lower my expectations (and price). 

The K4D with internal KAT4 tuner is now for sale for $5,500, no tax, free 
shipping to any USA address.
